CVE-2026-64312

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: pcrypt - restore callback for non-parallel fallback<br /> <br /> pcrypt installs pcrypt_aead_done() on the child AEAD request before<br /> trying to submit it through padata. If padata_do_parallel() returns<br /> -EBUSY, pcrypt falls back to calling the child AEAD directly.<br /> <br /> That fallback must not keep the padata completion callback. Otherwise<br /> an asynchronous completion runs pcrypt_aead_done() even though the<br /> request was never enrolled in padata.<br /> <br /> Restore the original request callback and callback data before calling<br /> the child AEAD directly. This keeps the fallback path aligned with a<br /> direct AEAD request while leaving the parallel path unchanged.
